Crystal Palace are eyeing Valencia centre-back Cristhian Mosquera.
The Sun says Palace see Mosquera as a replacement for captain Marc Guehi.
England international Guehi is attracting interest from Arsenal and Tottenham ahead of the January market.
Mosquera has broken into VCF's first team this season.
Capped at youth level by Spain, he also qualifies for Colombia who are keen to recruit him.
